CROSS REFERENCE TO RELATED APPLICATION(S)

The present application is a divisional of U.S. application Ser. No.11/058,820, filed Feb. 16, 2005, the disclosure of which is incorporatedherein by reference.

BACKGROUND OF THE INVENTION

The present invention relates to a device for use in connectingelectronic devices. More particularly, the present invention relates toa quick release assembly that enables a user to attach and detach anelectronic device such as a flat panel display from a mountingapparatus.

In the past people have placed video monitors and other electronicequipment on desks, tabletops, or upon other equipment such as personalcomputers or workstations. One drawback to these configurations is thereduction in available workspace taken up by the equipment. Anotherdrawback is the inability to place the equipment in a desired location.A further drawback is the potential for eye strain, neck strain and/or acumulative trauma disorder such as carpel tunnel syndrome from poorplacement of devices such as monitors and keyboards.

Different solutions have been provided in order to overcome theseobstacles. For example, in one solution, a monitor stand or printerstand elevates the apparatus over other equipment on a desk. While thismay free up workspace, it often places the equipment in an undesirablelocation. Another solution employs a mechanical extension arm to supportthe monitor. Extension arms free up workspace and allow users to placethe equipment where it is wanted. One such extension arm is shown anddescribed in U.S. Pat. No. 6,478,274, entitled “Arm Apparatus forMounting Electronic Devices,” which is fully incorporated by referenceherein. Another type of extension arm is shown and described in U.S.Pat. No. 6,409,134, entitled “Arm Apparatus For Mounting ElectronicDevices With Cable Management System,” which is fully incorporated byreference herein.

It is often desirable to obtain additional freedom of movement beyondthat provided by the extension arm. A tilting device can be used toaccomplish this goal. The tilting device is placed between the extensionarm and the equipment, allowing the equipment to rotate about one ormore axes. One such tilting device is shown and described in U.S. Pat.No. 6,505,988, entitled “Tilter for Positioning Electronic Devices,”which is fully incorporated by reference herein.

While such tilter devices are very useful for positioning the equipmentin a desired position, it may be difficult to rapidly detach theequipment from the tilting device and extension arm assembly. Forexample, a monitor may be secured to the tilting device by multiplescrews. It might take several minutes to disassemble all of the screws,detach the monitor, and then attach a new monitor. In many businesses,such as brokerage firms and other investment concerns, users requireongoing access to a working display unit. Disruptions, even those asshort as a few minutes, can seriously impact users' abilities to performtheir jobs. Thus, a quick release mechanism is needed to rapidly swapout a broken monitor for a working monitor. Furthermore, in order todetach the monitor without dropping it, the user needs to be verycareful when removing the screws from a conventional tilting device sothat the monitor does not suddenly detach and fall to the floor. It maybe difficult to the access the screws, as there may not be muchclearance between the monitor and the tilting device. Therefore, a needexists for a quick release mechanism to address these and otherconcerns.

DETAILED DESCRIPTION

The aspects, features and advantages of the present invention will beappreciated when considered with reference to the following descriptionof preferred embodiments and accompanying figures. In describing thepreferred embodiments of the invention illustrated in the figures,specific terminology will be used for the sake of clarity. However, theinvention is not intended to be limited to the specific terms soselected, and it is to be understood that each term selected includesall technical equivalents that operate in a similar manner to accomplisha similar purpose.

FIG. 1 illustrates an extension arm 100 that can be connected at one endto a mounting assembly (not shown) and attached to a tilting device 200at the other end. The mounting assembly may be of any desiredconfiguration, and may be affixed to a piece of furniture such as adesk, a wall such as a slat wall, a section of an office cubicle, etc.The tilting device 200 can be connected to an electronic device 300 suchas a flat panel monitor. A cable 302 is connected to the electronicdevice 300 at one end, and has a plug or other connector 304 at theother end. While the electronic device 300 is described below as a flatpanel monitor or other video monitor, the invention is not limited touse with such devices, and may be used with a wide variety of equipment,including non-powered equipment.

The extension arm 100 may be a conventional extension arm or any othersuitable mounting device. Preferably, the extension arm 100 is one ofthe types fully described in above-referenced U.S. Pat. Nos. 6,409,134and 6,478,274. As shown in FIG. 1, the extension arm 100 may include afirst endcap 102, an arm 104, a second endcap 108 and a forearmextension 110.

The first endcap 102 includes a housing attached to one end of the arm104 by, for example, pins. A shaft 118 or other connection device isadapted for connection to the mounting assembly. The shaft 118 may beintegrally molded with an endwall of the housing of the first endcap102. Alternatively, the shaft 118 may be securely attached to thehousing of the first endcap 102. The shaft 118 is preferably integralwith the first endcap 102.

The arm 104 is preferably formed of an upper housing 106 a and a lowerhousing 106 b. The upper housing 106 a and the lower housing 106 bdefine a chamber therebetween containing, for example, a gas spring (notshown). The gas spring is preferably adjustably mounted at one endwithin the first endcap 102 and at the other end to, for example, a ballstud mounted within the upper housing 106 a. The cable 302 may besecured within the arm 104 as shown and described in U.S. Pat. No.6,409,134. Alternatively, the arm 104 may include one or more externalcable ties in order to secure the cable 302 of the electronic device 300supported by the extension arm 100.

The second endcap 108 has a housing attached to the second end of thearm 104 by, for example, pins. A shaft may extend out of the top of thehousing of the second endcap 108 and optionally connect to the forearmextension 110. The forearm extension 110 includes a body 114 having aninterior channel, as well as a first end 112 and a second end 116.

When configured, the housing of the first endcap 102 andthe housing of the second endcap 108 point in opposite directions. Theshape of the parallelogram is retained by the gas spring within thechamber of the arm 104. Generally, the gas spring is sized so as to havea fixed length until an upward or downward force is exerted at thesecond endcap 108 that exceeds the gas spring's designed resistance.Thus, the gas spring retains the parallelogram shape when the only forceexerted at the second endcap 108 is the weight of the electronic device300. However, the gas spring permits the parallelogram shape to beadjusted when a user pushes the electronic device 300, which ispreferably coupled to the forearm extension 110 by means of the tiltingdevice 200, up or down.

The tilting device 200 can be directly connected to the endcap 108 or tothe second end 116 of the forearm extension 110, and is preferablyrotatable thereabout.

The post 250 on therelease plate 214 is preferably at least partly received in the opening233 of the adapter plate 212. The pair of arms 258 preferably contactthe pair of flat surfaces 242 a,b. At this point, the main body 245 andthe arms 258 preferably lie along the same plane.

FIG. 9( b) illustrates the rotating plate 216 after it is coupled toadapter plate 212 and the release plate 214. When the rotating plate 216is connected the release plate 214 is sandwiched between the rotatingplate 216 and the adapter plate 212. The bosses 256 on the front side246 of the release plate 214 are preferably securely received by thereceptacles or openings 274 in the rotating plate 216. Alternatively,the front side 246 of the release plate 214 may have receptacles oropenings that connect to bosses in the rotating plate 216. In fact, manydifferent types of fastening means are suitable to connect the releaseplate 214 to the rotating plate 216. The rotating plate should bepositioned so that the angled members 278 of the connectors 276 wraparound the second end 238 of the adapter plate 212. The angled members278 may contact the receptacles or regions 225 (if any) on the frontside 218 of the adapter plate 212. The tabs 232 on the adapter plate 212preferably cover the corners of the rotating plate 216 adjacent to thereceptacles or openings 274. The tabs 232 help retain the rotating platein place.

FIGS. 9( c)-(f) illustrate views of the assembled adapter unit 202.FIGS. 10( a)-(c) illustrate the adapter unit 202 releasably connected tothe tilter mount 206. Of course, it should be understood that therotating plate 216 may be riveted to the tilter mount 206 prior toattaching the rotating plate 216 to the release plate 214 and theadapter plate 212. The electronic device 300 may be secured to theadapter plate 212 before or after the whole adapter unit 202 isassembled. The rotating plate 216 permits the release plate 214, theadapter plate 212 and the electronic device 212 to rotate relative tothe tilter mount 206.

Once the tilter mount 206 is affixed to the rotating plate 216, thetilter head 204 can be connected to the tilter mount 206 using thetilter bar 208. It should also be understood that the tilter mount 206may be connected to the tilter head 204 and the tilter bar 208 before orafter being riveted or otherwise fastened to the rotating plate 216.After the quick release adapter unit 202 is properly assembled andconnected to the tilting device 200 and the electronic device 300, theelectronic device 300 preferably becomes adjustable about one or more ofthe X-, Y-, or Z-axes as shown in FIG. 2. However, while the rotatingplate 216 is described as permitting the electronic device 300 to rotateabout the Z-axis, other non-rotating connector plates may be utilized inwhich the electronic device 300 is not rotatable about the Z-axis. Insuch cases, the protrusion 270 on the rotating plate 216 is unnecessary,as are the washer channel 292 and the washer 296.

In order to detach the electronic device 300, the user preferably pulls,pushes or otherwise causes the post 250 or other release mechanism tomove within the opening 233 of the adapter plate 212 and toward theelectronic device 300. This, in turn, causes the main body 245 todeflect or move away from the rotating plate 216. The bosses 256 orother projections of the release plate 214 thus disengage from the holesor recesses 274 of the rotating plate 216. At this point, the rotatingplate 216 is at least partly disengaged from the adapter plate 212. Ifit has not already occurred, the angled members 278 of the connectors276 are then disengaged from the second end 238 of the adapter plate212. When the second end 238 of the adapter plate 212 points upward, therotating plate 216 may be fully removed by sliding it up and off of theadapter plate 212. The electronic device 300 can be placed on a stablesurface prior to disengagement in order to avoid potential damage to theelectronic device 300.

After detachment of the electronic device 300, the release plate 214preferably remains coupled to the adapter plate 212. Optionally, therelease plate 214 may be detachable from the adapter plate 212. Then thesame or a different electronic device 300 may be reattached to anextension arm or other mounting device by securing the rotating plate216 to the rest of the adapter unit 202 as described above.

While the release plate 214 permits a user to rapidly disengage therotating plate 216 from the adapter plate 212, there may be situationswhen it is desirable to prevent inadvertent or unwanted disengagement.For example, in a high traffic environment, one would like to discourageunauthorized personnel from tampering with the equipment. FIG. 11( a)illustrates a security mechanism in the form of a threaded fastener 298that is preferably receivable by the through-hole 244 in the adapterplate 212. As seen in FIG. 11( b), when the security mechanism isengaged, e. g., when the threaded fastener 298 is screwed into thethrough-hole 244, it is not possible to slide the rotating plate 216away from the adapter plate 212 and the release plate 214. While thesecurity mechanism is illustrated as the threaded fastener 298, manyother mechanisms may be used, including, but not limited to clips,clasps, hasps, locks, pins, wing nuts, etc. Thus, it becomes difficultfor an unauthorized user to quickly release the adapter plate 212 andthe monitor or other electronic device 300 from the rotating plate 216and the tilter mount 206.

It can be seen that the present invention provides a quick releasedevice which allows a user to easily attach and detach electronicequipment to an extension arm or other mounting device. It is notnecessary to remove or loosen hard to reach fasteners in order todisconnect the electronic device. In the brokerage firm example givenearlier, a defective monitor may be rapidly swapped for a new monitor,permitting the broker to continue trading without adversely affectinghis or her performance. The present invention also provides analternative security mechanism to prevent unauthorized or accidentaldetachment of the electronic equipment.

Adapter units in accordance with aspects of the present invention may beused with conventional extension arms and tilting devices. New tiltingdevices, including the tilter mounts described herein, may also be usedwith the adapter units to provide partial or full rotation of electronicdevices about one or more axes.

Although the invention herein has been described with reference toparticular embodiments, it is to be understood that these embodimentsare merely illustrative of the principles and applications of thepresent invention.
